"The Transitional Military Council announces the resumption of negotiations with the Alliance for Freedom and Change on Sunday at the presidential palace," the ruling army council said in a Saturday statement.

The latest developments came as the prosecutor general's office said ousted president Omar al-Bashir had been charged over the killings of protesters during anti-regime demonstrations that led to the end of his rule last month.

Thousands of people remain camped outside the military headquarters in Khartoum nearly four weeks after the armed forces toppled autocratic president Omar al-Bashir as demanded by a months-long protest movement.

A source in the prosecutor general's office confirmed reports on state media that acting public prosecutor general Al-Waleed Sayyed Ahmed had ordered Bashir's questioning under 'anti-money laundering and financing terrorism laws'.

Demonstrators reinforced their barricades outside the army headquarters in Khartoum after the two sides differed in talks Monday on the number of council seats for civilians and military representatives.
